To solve the problem, we need to address two parts: 1. Whether it is necessary for the transmitting antenna to be at the same height as the receiving antenna for line-of-sight communication. 2. Calculate the service area covered by a TV transmitting antenna that is 81 m tall when the receiving antenna is at ground level. ### Step 1: Understanding Line-of-Sight Communication Line-of-sight (LOS) communication requires that there are no physical obstructions between the transmitting and receiving antennas. It is not necessary for both antennas to be at the same height; as long as the line of sight is clear, communication can occur effectively. ...
